"After decades of experiments, U.S. Navy scientists believe they may have solved one of the world’s great challenges: how to turn seawater into fuel...The new fuel is initially expected to cost around $3 to $6 per gallon, according to the U.S. Naval Research Laboratory, which has already flown a model aircraft on it."

"This is essentially a carbon neutral process. The ocean is like a sponge for carbon dioxide in the air and currently has an excess amount dissolved in it. The process pulls carbon dioxide out of the ocean. It’s converted and burned as fuel. This releases the carbon dioxide back into the air which is then reabsorbed by the ocean. Rinse. Repeat."
